Step-by-step explanation:

3x + 2y = 9

- (3x + y = 6)

=> y = 3.

Therefore 3x + (3) = 6, 3x = 3, x = 1.

The solutions are x = 1 and y = 3.

Find the value of x.

koban [17]

Answer:

x = 110°

Step-by-step explanation:

The Outside Angle Theorem states that the measure of the angle formed by two secants or a secant and tangent from a point outside of a circle is half the difference between the two arcs.

This means that ½ (210 – x) = 50.

½ ( 210 – x ) × 2 = 50 × 2

210 – x = 100.

210 – x + x = 100 + x.

210 = 100 + x.

100 + x = 210.

100 + x – 100 = 210 – 100.

x = 110.

This value must be true because:

½ ( 210 – 110 ) = 50.

½ ( 100 ) = 50.

50 = 50.

The Wolfpack has won 11 games and lost 9 games this season. What percent of its games did the Wolfpack win?

defon

First, you need to find the total amount of games played by adding 11 and 9
$11 + 9 = 20$
Now you have to divide 11 by 20. If you wanted to find the percent of games lost, you would divide 9 by 20.
$11 \div 20$
answer: 55%
